Abstract
Description
- The present disclosure generally relates to agricultural harvesters and, more particularly, to systems and methods for controlling the position of a harvester implement of an agricultural harvester and displaying such position to the operator of the harvester.
- A harvester is an agricultural machine used to harvest and process crops. For instance, a forage harvester may be used to cut and comminute silage crops, such as grass and corn. Similarly, a combine harvester may be used to harvest grain crops, such as wheat, oats, rye, barely, corn, soybeans, and flax or linseed. In general, the objective is to complete several processes, which traditionally were distinct, in one pass of the machine over a particular part of the field. In this regard, most harvesters are equipped with a detachable harvesting implement, such as a header, which cuts and collects the crop from the field and feeds it to the base harvester for further processing.
- Conventionally, the operation of most harvesters requires substantial operational involvement and control by the operator. For example, a combine operator is typically required to control various operating parameters, such as the direction of the combine, the speed of the combine, the height of the combine header, the air flow through the combine cleaning fan, the amount of harvested crop stored on the combine, and/or the like. To address such issues, many current combines use an automatic header height control system that attempts to maintain a constant generally cutting height above the ground regardless of the ground contour or ground position relative to the base combine. For instance, it is known to use various electronically controlled cylinders to automatically adjust the height and position of the header relative to the ground based on sensor measurements received from a plurality of sensors. However, such systems may make it difficult for the operator to determine the current position and/or position of the header during operation of the combine.
- Accordingly, an improved system and method for controlling harvester implement position of an agricultural harvester that addresses one or more of the issues identified above would be welcomed in the technology. For example, an improved system and method for controlling harvester implement position of an agricultural harvester and displaying such position to the operator of the harvester would be welcomed in the technology.
- Aspects and advantages of the technology will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the technology.
- In one aspect, the present subject matter is directed to a system for controlling harvesting implement position of an agricultural harvester. The system includes a harvesting implement configured to be coupled to the agricultural harvester to permit adjustment of a current position of the harvesting implement relative to a field surface. Additionally, the system includes a sensor configured to capture data indicative of the current position of the harvesting implement relative to the field surface, a display device, and a controller communicatively coupled to the sensor and the display device. As such, the controller is configured to monitor the current position of the harvesting implement based on the data captured by the sensor. Furthermore, the controller is further configured to initiate display of a graphical user interface on the display device, with the graphical user interface displaying a first interface element associated with the current position of the harvesting implement relative to a second interface element associated with a reference position of the harvesting implement.
- In another aspect, the present subject matter is directed to a method for controlling harvesting implement position of an agricultural harvester. The agricultural harvester, in turn, includes a harvesting implement configured to be coupled to the agricultural harvester to permit adjustment of a current position of the harvesting implement relative to a field surface. The method includes receiving, with one or more computing devices, sensor data indicative of the current position of the harvesting implement. Furthermore, the method includes initiating, with the one or more computing devices, a display of a graphical user interface on a display device based on the received sensor data, with the graphical user interface displaying a first interface element associated with the current position of the harvesting implement relative to a second interface element associated with a reference position of the harvesting implement. Moreover, the method includes controlling, with the one or more computing devices, an operation of a component of the agricultural harvester to adjust the current position of the harvesting implement. Additionally, the method includes initiating, with the one or more computing devices, an adjustment of the positioning of the first interface element relative to the second interface element within the graphical user interface to reflect the adjusted current position of the harvesting implement.

For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
- In general, the present subject matter is directed to systems and methods for controlling harvesting implement position of an agricultural harvester. As will be described below, the present subject matter may be used with a combine or any other suitable agricultural harvester having a header or other harvesting implement for harvesting a crop within a field across which the harvester is traveling. For example, the header may extend in a transverse direction between a first side and a second side. Moreover, the header may extend in a vertical direction between a bottom end and a top end. As such, in several embodiments, the header configured to be coupled to the harvester to permit adjustment of the current position of the header in a plane defined by the transverse and vertical directions.
- In accordance with aspects of the present subject matter, the disclosed system may be configured to display a graphical user interface to the operator of the harvester indicating the current position of the header as the header is adjusted during operation of the harvester. In several embodiments, a controller of the system may be configured to receive sensor data indicative of the current position of the header. In this respect, the controller may be configured to initiate a display of the graphical user interface on a display device (e.g., a display screen within the cab) based on the received sensor data. Specifically, the graphical user interface may display a first interface element associated with the current position of the header relative to a second interface element associated with a reference position (e.g., a headlands position) of the header. Furthermore, the controller may be configured to control the operation of one or more actuators of the agricultural harvester to adjust the current position of the header (e.g., within the plane defined by the transverse and vertical direction) to maintain a generally constant cutting height above the field surface as the contour of the field surface changes. Thereafter, the controller may be configured to initiate an adjustment of the positioning of the first interface element relative to the second interface element within the graphical user interface to reflect the adjusted current position of the header.
- Referring now to the drawings,
FIG. 1 illustrates a partial sectional side view of theagricultural harvester 10. In general, theharvester 10 may be configured to travel across a field in a forward direction of travel (indicated by arrow 12) to harvest acrop 14. While traversing the field, theharvester 10 may be configured to process and store the harvested crop within acrop tank 16 of theharvester 10. Furthermore, the harvested crop may be unloaded from thecrop tank 16 for receipt by the crop receiving vehicle (not shown) via acrop discharge tube 18 of theharvester 10. Moreover, as shown, in the illustrated embodiment, theharvester 10 is configured as an axial-flow type combine in which the harvested crop is threshed and separated while being advanced by and along a longitudinally arrangedrotor 20. However, in alternative embodiments, theharvester 10 may have any other suitable harvester configuration, such as a traverse-flow type configuration. - The
harvester 10 may include a chassis ormain frame 22 configured to support and/or couple to various components of theharvester 10. For example, in several embodiments, theharvester 10 may include a pair of driven,front wheels 24 and a pair of steerable,rear wheels 26 coupled to theframe 22. As such, thewheels harvester 10 relative to the ground and move theharvester 10 in the forward direction oftravel 12. Furthermore, theharvester 10 may include an operator'splatform 28 having an operator'scab 30, acrop processing system 32, thecrop tank 16, and thecrop discharge tube 18 that are supported by theframe 22. As will be described below, thecrop processing system 32 may be configured to perform various processing operations on the harvested crop as thecrop processing system 32 transfers the harvested crop between a harvesting implement of theharvester 10, such as aheader 34, and thecrop tank 16. Furthermore, theharvester 10 may include anengine 36 and a transmission 38 mounted on theframe 22. The transmission 38 may be operably coupled to theengine 36 and may provide variably adjusted gear ratios for transferring engine power to thewheels 24 via a drive axle assembly (or via axles if multiple drive axles are employed). - Moreover, as shown in
FIG. 1 , theheader 34 and an associatedfeeder 40 of thecrop processing system 32 extend forward of theframe 22 and are pivotably secured thereto for generally vertical movement. In general, thefeeder 40 may support theheader 34. As shown inFIG. 1 , thefeeder 40 extend between afront end 42 coupled to theheader 34 and arear end 44 positioned adjacent to a threshing and separatingassembly 46 of thecrop processing system 32. Therear end 44 of thefeeder 40 may, in turn, be pivotably coupled to a portion of theharvester 10. In this respect, thefront end 42 of thefeeder 40 and, thus, theheader 34 may be be moved upward and downward along a vertical direction (indicated by arrow 48) relative to afield surface 49 to maintain a generally constant cutting height above thefield surface 49 as the contour of the field surface changes. As such, theharvester 10 may include one ormore lift actuators 102 configured to adjust the height of theheader 34 relative to thefield surface 49. - As the
harvester 10 is propelled in the forward direction oftravel 12 over the field with thecrop 14, the crop material is severed from the stubble by one or more knives (not shown) at the front of theheader 34 and delivered by a header auger 54 to thefront end 42 of thefeeder 40, which supplies the harvested crop to the threshing and separatingassembly 46. In general, the threshing and separatingassembly 46 may include acylindrical chamber 56 in which therotor 20 is rotated to thresh and separate the harvested crop received therein. That is, the harvested crop is rubbed and beaten between therotor 20 and the inner surfaces of thechamber 56 to loosen and separate the grain, seed, or the like from the straw. - The harvested crop separated by the threshing and separating
assembly 46 may fall onto acrop cleaning assembly 58 of thecrop processing system 34. In general, thecrop cleaning assembly 58 may include a series ofpans 60 and associated sieves 62. In general, the separated harvested crop may be spread out via the oscillation ofpans 60 and/or sieves 62 and may eventually fall through apertures defined by thesieves 62. Additionally, a cleaningfan 64 may be positioned adjacent to one or more of thesieves 62 to provide an air flow through thesieves 62 that removes chaff and other impurities from the harvested crop. For instance, thefan 64 may blow the impurities off the harvested crop for discharge from theharvester 10 through the outlet of astraw hood 66 positioned at the back end of theharvester 10. The cleaned harvested crop passing through thesieves 62 may then fall into a trough of anauger 68, which may be configured to transfer the harvested crop to an elevator 70 for delivery to thecrop tank 16. - Referring now to
FIG. 2 , a simplified, schematic view of one embodiment of theheader 34 described above with reference toFIG. 1 is illustrated in accordance with aspects of the present subject matter. As shown, theheader 34 extends in a transverse direction (indicated by arrow 72) between afirst side 74 and asecond side 76, with thetransverse direction 72 extending perpendicular to the direction oftravel 12. Moreover, theheader 34 extends in thevertical direction 48 between abottom end 78 and atop end 80. As will be described below, theheader 34 may be coupled to theharvester 10 such that the position of theheader 34 relative to theframe 22 of theharvester 10 may be adjusted within aplane 82 defined by the vertical andtransverse directions field surface 49 as the contour of thefield surface 49 changes. - In several embodiments, the
header 34 may include a plurality ofheader sections FIG. 2 , in the illustrated embodiment, theheader 34 include acenter section 84, afirst wing section 86, andsecond wing section 88. Specifically, in such an embodiment, thecenter section 84 may be coupled to thefront end 42 of thefeeder 40 such that thecenter section 84 is rotatable relative to thefeeder 40 about a longitudinal axis (indicated by circle 90) of theheader 34. Furthermore, thefirst wing section 86 may be pivotably coupled tocenter section 84 adjacent to thefirst side 74 at a pivot joint 92. Additionally, thesecond wing section 88 may be pivotably coupled tocenter section 84 adjacent to thesecond side 76 at a pivot joint 94. As such, the positions ofheader section field surface 49. However, in alternative embodiments, theheader 34 may have any other suitable number of sections and/or configuration. For example, in one embodiment, theheader 34 may include only a single section fixedly coupled to thefront end 42 of thefeeder 40 such that theheader 34 is only adjustable relative to theharvester chassis 22 in the vertical direction 48 (e.g., via the lift actuator(s) 102). - Moreover, one or more actuators may be configured to adjust the position of the
header 34 relative to theharvester frame 22 within theplane 82 defined by the vertical andtransverse directions field surface 49 as the contour of thefield surface 49 changes. For example, as described above, theharvester 10 may include one or more lift actuator(s) 102 (FIG. 1 ). Specifically, the lift actuator(s) 102 may be configured to raise and lower theentire header 34relative chassis 22 to adjust the overall cutting height of theheader 34. In addition, as shown inFIG. 2 , a pair oftilt actuators 104 are configured to rotate thecenter section 84 of theheader 34 relative to thefront end 42 of thefeeder 40 in the plane 82 (e.g., as indicated byarrow 106 inFIG. 2 ). Furthermore, first andsecond pivot actuators center section 84 of theheader 34 and the first andsecond sections header 34. As such, thefirst pivot actuator 108 may be configured to pivot thefirst section 86 of theheader 34 relative to thecenter section 84 of theheader 34 about the pivot joint 92 (e.g., as indicated by thearrow 112 inFIG. 2 ). Similarly, thesecond pivot actuator 110 may be configured to pivot thesecond section 88 of theheader 34 relative to thecenter section 84 of theheader 34 about the pivot joint 94 (e.g., as indicated by the arrow 114 inFIG. 2 ). As shown inFIG. 2 , such positional adjustments of theheader 34 and/or theheader sections field surface 49 changes in the direction oftravel 12 and along thetransverse direction 72. However, in alternative embodiments, any other suitable actuators may be used to adjust the position of theheader 34 to maintain a generally constant cutting height. - The
actuators actuators actuators - In accordance with aspects of the present subject matter, one or
more sensors 116 may be installed on theheader 34. In general, the sensor(s) 116 may be configured to capture data indicative of the position of theheader 34 relative to thefield surface 49 as theharvester 10 travels across the field in the forward direction oftravel 12. As will be described below, the data captured by the sensor(s) 116 may be used to control the operation of theactuators field surface 49 changes. - In general, the sensor(s) 116 may correspond to any suitable sensing device configured to capture data indicative of the position of the
header 34 relative thefield surface 49. For example, in several embodiments, sensor(s) 116 may correspond to height sensor(s) configured to data indicative of the distance (indicated by arrows 118) between theheader 34 and thefield surface 49. In one embodiment, the sensor(s) 116 may correspond to non-contact height sensor(s), such as laser sensor(s), radar sensor(s), ultrasonic sensor(s), and/or the like. Alternatively, the sensor(s) 116 may correspond to contact-based or mechanical height sensors. For instance, in one embodiment, the sensor(s) 116 may be coupled to a mechanical feeler(s) or a pivot arm(s) configured to contact thefield surface 49 and pivot up/down with changes in the field surface contour, thereby allowing the sensor(s) 116 to detect variations in thedistance 118 between theheader 34 and thefield surface 49. - Additionally, the

However, it should be appreciated by those of ordinary skill in the art that the disclosedsystem 100 may generally be utilized with agricultural harvesters having any other suitable harvester configuration and/or harvesting implements having any other suitable implement configuration. - As shown in
FIG. 3 , thesystem 100 may include acontroller 120 positioned on and/or within or otherwise associated with theagricultural harvester 10. In general, thecontroller 120 may comprise any suitable processor-based device known in the art, such as a computing device or any suitable combination of computing devices. Thus, in several embodiments, thecontroller 120 may include one or more processor(s) 122 and associated memory device(s) 124 configured to perform a variety of computer-implemented functions. As used herein, the term "processor" refers not only to integrated circuits referred to in the art as being included in a computer, but also refers to a controller, a microcontroller, a microcomputer, a programmable logic controller (PLC), an application specific integrated circuit, and other programmable circuits. Additionally, the memory device(s) 124 of thecontroller 120 may generally comprise memory element(s) including, but not limited to, a computer readable medium (e.g., random access memory (RAM)), a computer readable non-volatile medium (e.g., a flash memory), a floppy disc, a compact disc-read only memory (CD-ROM), a magneto-optical disc (MOD), a digital versatile disc (DVD), and/or other suitable memory elements. Such memory device(s) 124 may generally be configured to store suitable computer-readable instructions that, when implemented by the processor(s) 122, configure thecontroller 120 to perform various computer-implemented functions. - In addition, the
controller 120 may also include various other suitable components, such as a communications circuit or module, a network interface, one or more input/output channels, a data/control bus and/or the like, to allowcontroller 120 to be communicatively coupled to any of the various other system components described herein (e.g., theactuators FIG. 3 , a communicative link or interface 126 (e.g., a data bus) may be provided between thecontroller 120 and thecomponents controller 120 to communicate withsuch components - The
controller 120 may correspond to an existing controller(s) of theagricultural harvester 10, itself, or thecontroller 120 may correspond to a separate processing device. For instance, in one embodiment, thecontroller 120 may form all or part of a separate plug-in module that may be installed in association with theagricultural harvester 10 to allow for the disclosed systems to be implemented without requiring additional software to be uploaded onto existing control devices of the implementagricultural harvester 10. - Moreover, the functions of the
controller 120 may be performed by a single processor-based device or may be distributed across any number of processor-based devices, in which instance such devices may be considered to form part of thecontroller 120. For instance, the functions of thecontroller 120 may be distributed across multiple application-specific controllers, such as a navigation controller, an engine controller, an implement controller, and/or the like. - Furthermore, in one embodiment, the
system 100 may also include auser interface 124. More specifically, as will be described below, theuser interface 124 may be configured to display a graphical user interface to the operator of theharvester 10 indicating the current position of theheader 34 as theheader 34 is adjusted during operation of theharvester 10. As such, theuser interface 124 may include one or more display screens or display devices (e.g., an LCD screen(s)) configured to display a graphical user interface. In this respect, theuser interface 124 may be communicatively coupled to thecontroller 120 via thecommunicative link 126 to permit the data associated with the graphical user interface to be transmitted from thecontroller 120 to theuser interface 124. In some embodiments, theuser interface 124 may also include other feedback devices (not shown), such as speakers, warning lights, and/or the like, configured to provide additional feedback from thecontroller 120 to the operator. In addition, theuser interface 124 may include one ormore input devices 128, such as touchscreens, keypads, touchpads, knobs, buttons, sliders, switches, mice, microphones, and/or the like, which are configured to receive user inputs from the operator.

However, in alternative embodiments, theuser interface 124 may mounted at any other suitable location. - In several embodiments, the
controller 120 may be configured to monitor the current position of a harvesting implement, such as theheader 34, of theharvester 10. As described above, theheader 34 may include one ormore sensors 116 configured to capture data indicative of the position of theheader 34 relative to the field surface. In this respect, as theharvester 10 travels across the field in the forward direction oftravel 12 to perform a harvesting operation, thecontroller 120 may be configured to receive the captured data from the sensor(s) 116 (e.g., via the communicative link 126). Thereafter, thecontroller 120 may be configured to process/analyze the received sensor data to determine the position of theheader 34 relative to the field surface. For instance, thecontroller 120 may include a look-up table(s) and/or suitable mathematical formula stored within its memory device(s) 124 that correlates the received sensor data to the position of theheader 32. - As used herein, the "position" of the
header 34 relative to the field surface my correspond to any positional relationship between theheader 34 and the field surface. For example, as described above, in several embodiments, theheader 34 may be adjustable within a plane 84 (FIG. 2 ) defined by the vertical andtransverse directions header 34 may correspond to the distance between theheader 34 and the field surface in thevertical direction 48 and/or the rotation/orientation of theheader 34 in theplane 84 relative to the field surface. However, in alternative embodiments, the position of theheader 34 may correspond to any other suitable positional relationship, such as the fore-aft tilt angle. - In accordance with aspects of the present subject matter, the
controller 120 may be configured to display of a graphical user interface on thedisplay device 126 of theuser interface 124. In general, the graphical user interface may provide a visual indication of the current position of the header 34 (as determined by the received sensor data) relative to a reference position, such as the headlands position of theheader 34, to the operator of theharvester 10. Specifically, in several embodiments, the graphical user interface may display a first interface element (e.g., one or more lines) associated with the current position of theheader 32 relative to a second interface element (e.g., one or more lines) associated with the reference position of theheader 32. In this respect, the position of the first interface element on the graphical user interface relative the second interface element may provide the operator an indication of the current position of theheader 34 relative to the reference position of theheader 34. For example, in one embodiment, the position of the first interface element on the graphical user interface relative the second interface element may provide the operator an indication of the current position of theheader 34 relative to the reference position of theheader 34 in the plane 84 (FIG. 2 ) defined by the vertical andtransverse directions header 34 changes during the harvesting operation. - Furthermore, the first and second interface elements may include various interface element portions. As described above, in some embodiments, the
header 34 may include one or more header sections (e.g., theheader sections -
FIG. 4 illustrates an example view of agraphical user interface 130 that may be displayed to the operator of theagricultural harvester 10 on thedisplay device 126. As shown, thegraphical user interface 130 is displaying afirst interface element 132 having a firstinterface element portion 132A associated with thefirst wing section 86 of theheader 34, a firstinterface element portion 132B associated with thecenter section 84 of theheader 34, and a firstinterface element portion 134C associated with thesecond wing section 88 of theheader 34. Moreover, thegraphical user interface 130 is displaying asecond interface element 134 having a secondinterface element portion 134A associated with thefirst wing section 86, a secondinterface element portion 134B associated with thecenter section 84, and a secondinterface element portion 134C associated with thesecond wing section 88. Furthermore, in the example view shown inFIG. 4 , the reference position of theheader 34 corresponds to an operational position in which theheader sections vertical direction 48. As such, in the example view, the firstinterface element portion 132A is positioned below the secondinterface element portion 134A, thereby indicating that thefirst wing section 86 is below its reference position. Furthermore, the firstinterface element portion 132B is rotated relative to the secondinterface element portion 134B, thereby indicating that thecenter section 84 is rotated relative to its reference position. Additionally, the firstinterface element portion 132C is positioned above the secondinterface element portion 134C, thereby indicating that thesecond wing section 88 is above its reference position. -
FIG. 5 illustrates another example view of thegraphical user interface 130 shown inFIG. 4 . As shown, the reference position of theheader 34 corresponds to a headlands position which thecenter section 84 is lifted to a raised position relative to the field surface and thewing sections center section 84. Moreover, in the example view, thefirst interface element 132 is positioned belowsecond interface element 134, thereby indicating that theheader 34 is at an operational position. -
FIG. 6 illustrates yet another example view of thegraphical user interface 130 shown inFIG. 4 and 5 . As shown, like inFIG. 5 , the reference position of theheader 34 corresponds to the headlands position. Furthermore, in the example view, thefirst interface element 132 is superimposed over thesecond interface element 134, indicating that theheader 34 is at the headlands position. - The reference position of the
header 34 identified by the second interface element may correspond to any suitable position of theheader 34. For example, in the example view shown inFIG. 4 , the reference position corresponds to an operational position in which theheader sections vertical direction 48. In the example view shown inFIGS. 5 and 6 , the reference position corresponds to a headlands position. However, the second interface element may correspond to any other operational position (e.g., an operational position in which one or more of theheader sections harvester 10 may set or select the reference position of theheader 34. In such an embodiment, the operator may input such setting/selection to the input device(s) 128. Thecontroller 120 may then receive data indicative of the setting/selection from the user interface 124 (e.g., via the communicative link 126). However, in alternative embodiments, the reference position of theheader 34 may be set by the manufacturer. - Additionally, the first and second interface elements may correspond to any suitable interface elements. Specifically, in several embodiments, the first and second interface elements may correspond to lines. The line(s) of the first interface element may have a different color, texture, thickness, and/or the like to differentiate such line(s) from the line(s) of the second interface element. For example, in the example views shown in
FIGS. 4-6 , the first interface element corresponds to three thick lines, with each line being associated with one of theheader sections header sections FIG. 6 , the lines of thefirst interface element 132 are shown as hollow boxes to illustrate thefirst interface element 132 being superimposed over thesecond interface element 134. Moreover, in some embodiments, the line(s) of the one of the first or second interface elements may be solid and the line(s) of the other of the first or second interface elements may be dashed. However, in alternative embodiments, the first and/or second interface elements may correspond to numbers (e.g., percentage(s) and/or angle(s)), bars of a bar graph, and/or the like. - Referring back to
FIG. 3 , thecontroller 120 may be configured to control the operation of one or more components of theagricultural harvester 10 to adjust the current position of theheader 34. As described above, theharvester 10 may include theactuators header 34 relative to the field surface (e.g., in a plane 84 (FIG. 2 ) defined by the vertical andtransverse directions 48, 72). Moreover, as described above, thecontroller 120 may be configured to monitor the position of theheader 34 relative to the field surface as theharvester 10 travels across the field in the direction oftravel 12. In this respect, thecontroller 120 may be configured to control the operation of theactuators header 34 to maintain a generally constant cutting height as theharvester 10 during the harvesting operation. For example, based on the monitored position of theheader 34, thecontroller 120 may be configured to transmit control signals to theactuators actuators header 34 within theplane 84 to maintain a generally constant cutting height across thetransverse direction 72 as theharvester 10 travels in the forward direction oftravel 12. - Additionally, the
controller 120 may be configured to initiate adjustment of the position of the first interface element during the harvesting operation. More specifically, when the position of theheader 34 or one theheader sections controller 120 may be configured to initiate an adjustment of the positioning of the first interface element relative to the second interface element within the graphical user interface to reflect the adjusted current position of theheader 34. For example, as described above, in some embodiments, the reference position of theheader 34 as identified by the second interface element may correspond to the headlands position. In such embodiments, when theheader 34 is moved from an operational position to the headlands position, thecontroller 120 may be configured to initiate an adjustment of the position thefirst interface element 132 within the graphical user interface from a location below the second interface element to being superimposed over the second interface element. - Displaying a graphical user interface having a first interface element associated with the current position of the
header 34 relative to a second interface element associated with the reference position of theheader 34 may provide the operator a visual indication of the current position of theheader 34. Moreover, adjusting the position of the first interface element relative to the second interface element as the position of theheader 34 is adjusted relative to the field surface may further provide operator a visual indication of how the current position of theheader 34 is being adjusted during the harvesting operation. - Referring now to
